Oubre will reportedly undergo further evaluation to determine if he can keep playing with the injury.
The 25-year-old was kept out of Saturday's encounter with the Houston Rockets and has now missed two consecutive games for Golden State. Oubre was sidelined for five straight matchups earlier in April after reaggravating the issue, but he returned on April 19 and had reportedly been trying to play through the pain.
Oubre is averaging 15.4 points, six rebounds, 1.3 assists, and one steal in 55 games this season while averaging 30.7 minutes per contest.
The Warriors are in a race to secure at least a play-in berth. The club occupied the final play-in seed entering Saturday's slate but were just three games ahead of the New Orleans Pelicans. Golden State will have eight games left to play this season after Saturday.
